Egg In Vinegar Lab Report

The purpose of the experiment was to determine what happened during osmosis and diffusion across membranes by using a fresh hen’s egg.

When the eggs were just placed in 200 mL of water, their masses greatly increased. The inside of the eggs have a higher solute concentration than the water outside the cell. Water

In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg. The container was built to decrease the impact of the force at each drop. The container was able to successfully protect

For each of the condition, about 35 milkweed bug eggs will be placed in clear container (5”x7”x4”) with a fine netting between the lid of the container and the container walls. The netting prevents the milkweed bugs from escaping while allowing for air to come in. Each container

First of all, an alka-seltzer is an a little tablet that helps with multiple pain. For example, alka-seltzer helps with migraines, headaches, sinus headaches, muscle pain, and symptoms of pain. Alka-seltzer contains aspirin, sodium, hydrogen carbonate, citric acid, natural flavors, and artificial flavors. These are just some of the ingredients. When an alka-seltzer dissolves it releases all of the medicine. Alka-seltzer is an easy pain killer.

Title: THE BALLOON INFLATION REACTION Introduction: Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.

The Pop Rocks have a very small amount of carbon dioxide in them. When the Pop Rocks are in your mouth they dissolve and the carbon dioxide is released making the pieces of candy explode in your mouth. When the Pop Rocks come in contact with the soda, the gas in the Pop Rocks escape after disolving and the carbon dioxide escapes from the liquid into the balloon. When this happens it causes the gas to make the balloon expand bigger and bigger until the air can escape.

Brine Shrimp Lab Reflection After performing the Brine Shrimp Inquiry lab my group found that .5% salinity of 50 mL of water was the ideal salinity for hatching brine shrimp. To figure out what salinity was ideal we tested three different levels of salinity. The first thing we did when we began the lab was choose three different salinities to test. My group choose .5%, 3%, and 5%, next we choose the amount of water that would be in each dish; we decided on 50 mL of water. We then calculated the amount of salt to put in each dish.

If I had a household product labeled sodium bicarbonate, I would add an acidic substance and expect bubble to be created. As we know acid reacts with bubbles when combined with sodium bicarbonate. 2.

H2CO3 The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due to carbon dioxide escaping from solution. One of the reasons people love to drink

Ali Atwi : Internal assesment – calculating of the concentration of ethanoic acid in vinegar AIM : To calculate the concentration of ethanoic acid CH3COOH in vinegar using stoichiometric equations, ( Yamaha brand ) Introduction : I personally like to add a little bit of vinegar on my food because it makes it taste better, yet I know that vinegar contains acid, and I also know the consequences of highly concentrated acid intake, like severe itching and stomach ache, vomiting. Venigar contains a small percentage of ethanoic acid Ch3COOH. This practical aims to find out the concentration of the of the vinegar against a standard solution of sodium hydroxide soloution of concentration 0.1 mol dm3 through acid-base titration, the label on the bottle says 6%.

NaHCO3 baking soda and vinegar CH3COOH forms CO2. 5. What happened when starch was used? Based on your observations, how could iodine be used to test for the presence of starch?

Each group was assigned a different percent of sucrose solution out of the four variables; 0% , 5%, 10%, and 15%. After we filled the beaker we then got two potato cores. Once we had the cores we cut the skin off the ends. Following this we then cut the two potato cores into four 2.00 cm potato cores. After they were cut into 2.00 cm each we found the mass.

Objectives In this lab, you will investigate the percent composition by mass of CO2 in Alka-Seltzer® tablets. In addition, you will find out how much CO2 is released into the atmosphere as 2 Alka-Seltzer® tablets chemically react in vinegar. Procedure 250-mL beaker 100-mL graduated cylinder Scale 60 mL of Vinegar 2 Alka-Seltzer® tablets

CLAIRE MUNTING 29/01/2018 Criterion C EFFECTS OF SURFACE AREA OF CALCIUM CARBONATE UPON RATE OF REACTION Calcium Carbonate Chips 1 Introduction: Within the current investigation, the effects of the surface area of Calcium Carbonate (CaCO3) in combination with Hydrochloric acid (HCl) upon its rate of reaction. CaCO3, commonly referred to as limestone, is an organic substance and is, in a sense, the crystallised “carbonic salt” of the element, calcium2. In addition to being a salt, the pH level of Calcium Carbonate is 9.91, and it is therefore, a basic substance, due to the fact that it is comprised of a pH level higher than 7, which is neutral3. HCl, however, is the bodily acid found in the stomach of human beings.
